Metallurgical transport vessel construction

ABSTRACT

A transport vessel for the transportation of metallurgical melts or molten metals includes a cylindrical ring at each end having a journal extending radially outwardly from each side which engages in open topped bearing bushings on a forked end of a rotatable journal. The rotatable journal is supported on a pedestal on a mounting platform which, for example, may be a wheeled car. The transport vessel includes a ring spaced inwardly from the end of the cylindrical end formation providing a mounting for receiving a detachable end plate which may be secured to the ring, for example, by securing bolts. The end plate is reinforced by intersecting reinforcement ribs, and it includes a mortar charging opening.

METALLURGICAL TRANSPORT VESSEL CONSTRUCTION SUMMARY OF THE INVENTION This invention relates. in general. to the construction of metallurgical vessels and. in particular, to a new and useful oblong transport vessel for molten metals having a cylindrical formation at each end with a charging aperture which is closed by a removable end plate and which also includes a transversely extending journal for supporting the vessel in receiving bearings of a rotatable journal.

The invention deals with the construction of a vessel of a type which is employed for transferring liquid iron from the blast furnace to the steel mill or to the foundry. The lining of such vessels must be renewed at intervals of from 2 to 3 months, for example. This may require a period of about 2 weeks or to percent of the operating time for such vessels. The renewal of the lining has heretofore taken so long because the old lining had to be removed through the charging aperture and a new lining introduced through the same aperture. The present invention provides a construction of a transport vessel which can be quickly separated from its supporting undercarriage and can be operated upon to provide a freshly lined vessel which may be easily returned to operation.

The present invention is an improvement in transport vessels inasmuch as it provides a construction which includes a cylindrical end portion having a detachable end plate fitted therein. Such a construction shortens the time for the breaking out and relining of such vessels and thus reduces the down time.

The end plate is detached from the transport vessel as soon as the vessel is separated from its supporting undercarriage. It is then possible to immediately start breaking out the old lining from the transport vessel by operations carried out from the charging aperture at each end. As soon as the vessel is 1 clear of the supporting undercarriage, the installation of the new lining can be started. The end covers are such that they can be removed to expose the cylindrical opening so that the installation of the new lining can be started from each end.

The end plates advantageously include one or more mortar charging connections in order to fill the gap between the lining and the end plate. Such connections are of importance especially when the end plates are designed as arched bottoms. The lining of the end faces may also be carried out from the inside after the end plates have been installed. In the preferred i arrangement of the invention, the transport vessel is provided with cylindrical end sections having rings flanged to the interiors thereof which provide amounting for the end plates which may be detachably secured to such rings.

Accordingly, it is an object of the invention to provide an improved metallurgical transport vessel which includes acylindrical end formation having an interior ring flanged thereto and providing a mounting for a detachable end plate.

A further object of the invention is to provide a transport vessel which is simple in design, rugged in construction, and

v economical to manufacture.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of this specification. For a better understanding of the invention, its operating advantages and In the drawings:

of FIG. 3; and

FIG. 3 is an end clevational viewof the transport vessel indicated in FIG. 1, but shown on an enlarged scale.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, in particular, the invention therein comprises a transport vessel generally designated 1 which includes an enlarged cylindrical main section la, a frustoconical intermediate end section lb and an end cylindrical section 4. The cylindrical section 4 is provided with a plurality of transversely or radially extending journal elements 3 which are adapted to engage in open top bearing support shells 5 formed as forked ends of a rotatable journal 2. The journal 2 is supported between pedestals 20 and 22 which are carried on a mounting stand 16 which is supported on a railway flat car platform 24. Coupling means 17 are provided to secure the base 16 in a position aligned with the axis of the transport vessel or to permit release thereof for facilitating the freeing of the transport vessel 1. Journal covers 5a may be easily lifted to permit upward withdrawal of the transport vessel journals 3.

In accordance with the invention, the transport vessel 1 has a ring 7 flanged to its interior at a spaced location from the outer end 40. The ring 7 provides a mounting for a detachable cover or end plate generally designated 6. The end plate 6 may be secured to the flanged ring such as by bolt members (not shown) which extend through openings 26.

The end plate 6, in accordance with the invention, is procircular cross section of the central cylindrical portion, said frustoconical portion having its larger end fixedly secured to. an end of said central cylindrical portion, a cylindrical outer end portion of circular cross section, and of the same diameter. as that of the smaller end of the frustoconical portion, one end i of saidv cylindrical end portion being fixedly secured to the smaller end of said frustoconical portion, a ring secured to the interior of said cylindrical end portion and located at a spaced location from the end thereof, a detachable end plate carried by said ring, and a journal extending outwardly from said cylindrical end portion at each side thereof for supporting said vessel.

2. A transport vessel, according to claim 1, wherein said end plate includes at least one mortar charging connection.

3. A transport vessel, according to claim 1, wherein said; ring includes a plurality of openings for receiving bolts for securing said end cover in position, said end cover having a, plurality of intersecting reinforcing ribs extending across the; exterior surface thereof and at least one mortar charging connection. 

1. A refractory-lined oblong transport vessel for molten metals which is adapted to rest on an undercarriage pedestal at each of its ends, comprising a hollow body having a central cylindrical portion of circular cross section, a frustoconical intermediate portion having its larger end of the same size as that of the circular cross section of the central cylindrical portion and its smaller end of a size much smaller than that of the circular cross section of the central cylindrical portion, said frustoconical portion having its larger end fixedly secured to an end of said central cylindrical portion, a cylindrical outer end portion of circular cross section, and of the same diameter as that of the smaller end of the frustoconical portion, one end of said cylindrical end portion being fixedly secured to the smaller end of said frustoconical portion, a ring secured to the interior of said cylindrical end portion and located at a spaced location from the end thereOf, a detachable end plate carried by said ring, and a journal extending outwardly from said cylindrical end portion at each side thereof for supporting said vessel.
